Slate Insights

What is Slate?

Slate is a metamorphic rock, meaning that it started out as one type of rock and “morphed” into something different. In the case of slate, it starts out as shale or mudstone. Compression and heat then change the minerals so the end result is slate.


When treated with a color enhancing sealer, many slate tiles come alive with rich colors.

Slate is quarried around the world. The largest slate quarry is in North Wales. However, Portugal, Germany and the United States, along with multiple other countries also have slate quarries.

Slate has many uses but is mainly used for roofing, countertops, building facades, plus indoor and outdoor flooring, and garden accents and decorations.

Slate Color Enhancing

Slate Restoration

We can resolve any problems associated with your slate surfaces, such as dullness, chipping, scratches or other damage, and apply color enhancing or topical sealers to achieve the finish you desire.

Slate Repairs

If your slate surfaces have become cracked, chipped, scratched, or otherwise damaged, Patriot Stone Restoration can resolve these issues, most often without need of replacement. We can also take care of any grout problems you may have with our deep-cleaning, sealing and repair services.

Slate Cleaning and Restoration

Over time, thick layers of soap residue, waxes, and other topical coatings can dull and hide the beautiful inherent colors and untamed charm of your slate floors and surfaces. The qualified technicians at Patriot Stone Restoration can strip away this dull buildup, as well as the dirt and contaminants it often traps, to reveal the naturally stunning surface underneath.

Cleft Finish Slate Expertise

In the wrong hands, your beautiful cleft slate surfaces can be easily damaged during deep cleaning or restoration. Patriot Stone Restoration has the knowledge of and expertise in the proper equipment, techniques and powders needed to ensure the lasting beauty of your installation. We are always available to answer any questions and to discuss the specific requirements of your unique slate surfaces.

Sealing & Color Enhancing

We can treat your slate with premium quality solutions…

Most — though not all — varieties of slate are virtually waterproof. This may mean sealing your slate is unnecessary, but it doesn’t necessarily mean sealing is undesirable. There are color enhancing sealers and coatings which can make the natural colors of your slate surfaces emerge more vibrantly. And, of course, for those types of slate which are not as waterproof as they could be, applying a sealer can further support their resistance to staining agents and weather conditions. 

Patriot Stone Restoration not only provides these services, we are also happy to discuss your specific needs and educate you on the best way to care for your unique slate type and installation. We are proud to recommend and supply stone-safe solutions for your regular cleaning and maintenance needs as well.

Natural Stone Cleaning & Care

Some helpful tips:

  • Always use a stone safe cleaner on your stone surfaces.

Does Slate Need Maintenance?

The short answer is yes, slate does require maintenance.  Regular cleaning with a stone safe cleaner is a great for simple day-to-day maintenance, but over time, floors can develop grout lines that just won’t come clean, shiny scratches, and increasingly obvious traffic patterns. Countertops can become scratched, dull and etched. 

As these problems develop, you become more and more dissatisfied with the appearance of the floors and other surfaces until it’s time for another round of professional restoration. Ask about our regularly scheduled maintenance program which keeps your floors looking great all the time, without the need for periodic restoration.
